Por lo tanto and por consiguiente are more formal than así que. They are useful in explanations, essays, reports and logical arguments.

Formal result Estaba enfermo; por lo tanto, no asistió. He was sick; therefore, he did not attend. Por lo tanto introduces a logical conclusion.

Punctuation and word order

Consecutive connectors often appear between two clauses. In formal writing, connectors such as por lo tanto and por consiguiente are often separated with punctuation.

Pattern Spanish example Note
Comma before everyday connector Era tarde, así que volvimos. Common with así que.
Comma before por eso No había entradas, por eso nos fuimos. Common in neutral writing.
Semicolon + formal connector Los datos son incompletos; por lo tanto, no podemos decidir. Useful in formal writing.
Connector at the beginning Por lo tanto, necesitamos otra solución. Introduces a conclusion from previous context.

Everyday, neutral and formal connectors

Consecutive connectors differ in tone. Choose the connector according to the type of text or conversation.

Typical mistakes with Spanish consecutive conjunctions

  • Confusing cause and result: porque gives the reason; por eso gives the result.
  • Using por eso where formal writing needs por lo tanto: por eso is neutral; por lo tanto is more logical and formal.
  • Using tan with nouns: say tanta gente, not tan gente.
  • Using tanto with adjectives: say tan difícil, not tanto difícil.
  • Forgetting punctuation in formal writing: por lo tanto and por consiguiente are often set off with punctuation.
  • Confusing result and manner with de modo que: context decides whether it means “so” or “in such a way that”.
